MODERN, EASY TO USE INTERFACE
There are two basic and advanced interfaces: with or without GLP information, real time, and data logging.
COLOR LCD GRAPHIC DISPLAY
Graphic display, and custom color profiles. The display allows real-time and virtual keys to support intuitive user experience.
TOUCH KEYBOARD
Capacitive touch keyboard for precise navigation of menus and screens. There are 4 frequently used dedicated keys including calibration and measurement mode switching and 4 virtual keys that change when in use. Capacitive touch technology ensures buttons never get stuck.
USB PORT
Data can be transferred to a computer with a USB cable and HI92000 software.
DATA RECORDING
– Three recording modes are available on the HI5221: automatic, manual, and AutoHold.
– Manual and automatic recording of up to 100 batches with a maximum of 50,000 records/lot, for a total of up to 100000 data points.
– Automatic recording feature to save data by time and sampling interval.
CAL Check™
Hanna Instruments’ exclusive CAL Check™ feature alerts the user to problems during calibration such as contaminated buffers or probes that need to be cleaned or replaced.
AUTO CALIBRATION
– Calibration has automatic, semi-automatic, direct, and direct manual input buffer receiving options
– Automatic calibration is available for 2 points at 0% and 100% saturation or 0 mg/L and 8.26 mg/L. An optional user benchmark is available for a user-defined value.
